Joern Kottmann reopened UIMA-2225:
----------------------------------
There is one more issue with the action bars.
> Reusing of ICasEditor instances doesn't surrounding update views
> ----------------------------------------------------------------
>
> Key: UIMA-2225
> URL: https://issues.apache.org/jira/browse/UIMA-2225
> Project: UIMA
> Issue Type: Bug
> Components: CasEditor
> Reporter: Joern Kottmann
> Assignee: Joern Kottmann
> Fix For: 2.4.0SDK
>
>
> If the amount of editor in the workbench is restricted to a certain number,
> eclipse will reuse already existing editors and sets a new input.
> In the case an editor input is change all the ICasEditor sensitive views are
> still bound to the old editor input.
> The AnnotationEditor can be reused by the eclipse workbench, and also view
> switches can change the way an input CAS is displayed.
> The AnnotationEditor itself can deal with any type of CAS sofa, if it is a
> text it is displayed and if not an appropriate message page is displayed. The
> surrounding views don't have a mechanism to deal with changing editor input
> or changing CAS views.
> Therefore we should extend the page book style annotation editor views with a
> mechanism to have an additional layer of pages to cover the following cases:
> a) Show view implementation and cas contents (Maybe destroy it and re-create,
> reusable view
> pages are error prone to implement)
> b) View cannot be displayed because the document is not available (document
> failed to load)
> c) View cannot be displayed because the CAS view is incompatible with this
> view
